. Corr'iELD L. .l'oir lmfcitizens of the l es. residing iit Dayton, in the of hiontgomcry and State of Ohio, invented certain net and, useful lin- F rinitur Drinking-Cups; and we do tier are the following to he a full clear. and exact description of the invention, such as will enable other skilled in the art to -which it nppertiiins to make and use the same. reference being had to ihe'ucconipanyiiig drawings, and to the letters and figures of refercnce marked thereon, which form a part of his specification. i I 5 (Eur invention relates to new and useful 'mprovenients in sanitary drinking founl e object of the invention is to provides 2e iliting iountain which is attachable to any water faucet supplied from the city nisir and which does not require to be de- 1 tom the faucet when it is desired Water in large quantities or for 25 in other words the device bei manent fixture without interferthe. quick dinning of water for any imposes end our invention corn rises a llf'l'i furnishes water for rinking -;-rtiiin pressures, but which may iion in which the titer will be the drinking fountain for i hereinafter more fully apfOllUWlnQ description in conthe accompanying drawings.

the drinking tube. on and drawings similar indicate corresponding having a screw-threaded bib 2 to which our iinproveddrinking fountain is attached. The integral parts of the fountain coifsist of a cup 3 from which p ojects a lower discharge spout & and an internal apertured hose 5 which extends inwardly from an internal screw-threaded opening 5. Within the cup 3 is a drinking tube or jet 12 supported in the upper end of a casing 8 which is integral with or extends from the boss 5 on the inside of the cup. The screw-threaded opening leading to said boss receives one end of an elbow 6 the other end of which is attached to the bib 2 by means of 2i coupling 7 and thus is obtained the connection between the faucet and drinking fountain hereinbefore referred to. The casing 8, as

shown in Fig. l, is provided with :1- lower.

discharge openin 14 which forms a valve seat for a disc urge valve 9 normally maintained on said seat by the weight of said valve. The said valve 9 is integral with an uppervnlve 11 which is adapted to engage a seat 13 to close the opening in the drinking tube or jet 12. The upper valve 11 is somewhat smaller than the bore of the casing 8 to provide a passageway 10 to: t e water to flow around said valve to the E a 12. The body or intervening part of the valves 9 and 11 is of two diameters, thereby forming an annular shoulder on the valve body. 'When the water is turned off at the faucet, the valve member rests in the position shown in Fig. 1 and closes the lower opening 14. .When the water is turned on slightly or the force of which does not exceed the Weight of the valve member, said water passes to the jet or drinking tube 12 through the annular passageway 10. When, however. the water is turned on to a greater extent or the force of which exceeds the weight of said valve member, the pressure of the water acting on theennular shoulder 15 will elevate the valve hotly thereby shutting ofi" the supply to the jet l2 and allowing the water to pass out or" the lower spout 4-. It will, therefore. be seen that when the Water desired for drinking purposes the faucet 1 need only be turned slightly and the water allo ved suliicient force to rise above the tube 12, hu't when the water wanted in larger quantities or for other purposes it may be discharged into a receptacle through the spout ii: by opening the faucet to ll greater extent. It will also be noted that the vunder excessive pressure trated a modification in through the jet 12 when thereby maintaining a uniform et for drinking purposes and preventing a waste of water and inconvenience to the person drinking.

In.-Figs. 5 to 8, inclusive, we have illusthe form and arrangement of the valve. The valve-body is placed in a horizontal position and the ortiori 9 is exposed directly to the action 0 the water and is adapted to engage a seat 14 formed on the-inner end of the connecting elbow 6. The inner end of the valve body forms a valve 11 in conjunction with a seat 13 formed in the casing 8 in line therewith. The body of said valve has a longitudinal opening l0 therethrough which establishes a communication between the elbow 6 and the drinking tube 12 when the force of the water is not suiiicient to' shift said valve from the position shown in Fig. 5 to that shown in Fig. 8. A spring 15* normally holds the valve 9 on its seat until the force of the water exceeds the tension of the spring.

Having water cannot pass described our invention, we claim.

1.-In a device of the character specified, acasing having a main water inlet and'upper and lower discharge openings, and a valve member mounted therein actuated by the water pressure and adapted to control the assa e of water through one or the other of said ischarge openings according to the force exerted thereon by the water.

2; A drinkin fountain adapted to be permanently attac ied to a water faucet and comprising a shell having an internal boss provided with horizontal and vertical open- I ings communicating one with the other, a

drinking tube communicating with the vertical opening, and a fluid actuated valve controlling the water passage to said drinking tube and to the lower opening, said valve normally closing the lower openin and establishing a communication with t e drinking tube.

3. In a device of the character specified, a casing having a main water inlet and outlet and a jet for drinking purposes, and a fluid actuated duplex valve member adapted to normally close the main outlet and maintain a communication with the drinking jet, the position of said valve member depending upon the force of the incoming water.

4. In a device of the character specified, a casing having a main water inlet and outlet and a jet for drinking purposes, and a valve member adapted to normally close outlet and to maintain a communication between the main inlet and said drinking jet, said valve member having an annular shoulder against which the water impinges to reverse said valve member when the force of the water exceeds the weight of member.

5. In a device of the character specified, a casing having a main water inlet and outlet and a drinking jet, a valve member having an enlarged portion lying within the entrance to the drinking jet and providing an annular passage therearound and an annular shoulder therebelow said valve member being adapted to normally close the main outlet and maintain a communication between the drinking jet and the inlet and to be reversed when the force of the water exceeds the weight of said valve member.

6. The combination with a valve casing having a low pressure discharge opening and a high pressure discharge opening, of a duplex valve normally closing the high pressure opening and adapted to close the low ressure discharge opening" when actuated y the fluid pressure.

In testimony whereof -we atlix our signatures, in presence of two witnesses.
